Question

thw ratio of diffusion of hydrogen and oxygen is

Answer 1

Answer : The ratio of diffusion of hydrogen and oxygen is, 4 : 1

Solution : Given,

Molar mass of $H_2$ = 2 g/mole

Molar mass of $O_2$ = 32 g/mole

According to the Graham's law, the rate of diffusion of gas is inverse proportional to the the square root of the molar mass of the gas.

$R\propto \sqrt{\frac{1}{M}}$

or,

$\frac{R_{H_2}}{R_{O_2}}=\sqrt{\frac{M_{O_2}}{M_{H_2}}}$

Now put all the given values in this expression, we get

$\frac{R_{H_2}}{R_{O_2}}=\sqrt{\frac{32}{2}}=\sqrt{\frac{16}{1}}=\frac{4}{1}$

Therefore, the ratio of diffusion of hydrogen and oxygen is, 4 : 1
